Wmmmm'" I v mmmummnmnw l2 (\b x auvento'z UNITED STTES EAEEN orrionEBNEST W. GOODEY, F PHILADELPHIA, PENNSYLVANIA"- JOINT FOR ROLLED METALBARS To all whom it may concern:-

Be itknown" that I, Ennns'r W. GOODEY,

a citizen of the United States, residing at Philadelphia, in the-countyof Philadelphia and State of Pennsylvania,'have invented certain new anduseful. Improvements in "Joints for Rolled Metal Bars, of which thefollowing is a specification.

Y My invention relates to improvements in joints for rolled metal bars,the object of the invention being to so construct intersecting bars of ametal frame that they may be com- 'pletely interlocked and withoutcutting entirely through either of the members.

A further object is to provide an improved joint which enables a stronginterlock between the bars'of a frame at right angles to each other, andwhich is especially adapted for use in connection with window, skylight,and other glass structural work.

\Vith these and otherobjects in view, the

' invention consists .in certain novel features ofconstruction andcombinations and arrangements of parts, as will be more fullyhereinafter described and pointed out in the claims;

In the accompanying drawings: Figiire 1,

is 'a fragmentary view in side elevation illus trating the bar 1 of myimproved joint. Fig. 2,.is a similar view of the other bar 2. Fig. 3,illustrates incross section the bars shown in Figs. '1 and 2. Fig. 4c,is a view in elevation of bar 1, showing it as it is shaped to receivethe bar 2, the latter being shown in section. Fig..5, is a view insection on the'line 55 of'Fig. 4:. Fig 6, is

a view similar to Fig. 4, but showing the joint as itis completed, andFig. 7, is a perspective View of the completed joint.

While 'I shall hereinafter refer to the bar .1 as the vertical bar, andthe bar 2 as the horizontal bar, these terms are used merely forc'onvemence of description, as

' they may, offcourse, be exactly reversedif- .45

. a I y I. bar 2. The curved bead porti n 4 of r"1 is cutout forming acurved opening 7 registering with the opening 6, and ada ted to receivethe rounded head portion & 0 bar 2. The web portion 3 of bar 1 is slitlongitudinally as shown at 8 and 9 forming two tongues 10- and 11 atopposite sides of the opening 6'. Bar 2 is provided in its web' portionat its' free edge witlra notch 12 which is equal in length to thedistance between the openings 6 and the free edge of the web portion ofthe bar 1. W'hen the. bars are thus formed. the tongues 10 and 11 arebent at an angle to the web of bar 1 as shown in Figs. 4 and 5. Bar 2 isthen inserted through. the opening thus made, and first assumes theposition shown in Figs.

4 and 5/ When in thisposition, bar 2 is given a quarter turn to bringits rounded bead portion 4 into the curved 013611115 7 and its notch 12engages the .web portion of bar 1. When in this position, the tongues 10and 11 are bent back to their normal po-. sition, and the parts will'beas shown in Figs. 6 and 7. That is .to say, the parts will be securelylooked as they cannot move either longitudinally or laterally relativeto each other. and neither of the bars will be cut entirely through.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot: limit myself to the precise details set forth, but consider my-.self at. liberty to make such changes and alterations as fairly fallwithin the spirit I and scope of the appended claims. 3

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

.1. The combination with twobars. both tioned bar, substantially asdescribed.

2. The combination with-two bars, both bars having fiat .web portionsand rounded beadsther'eon, one bar having a longitudinal bead.eatending'b'eyond the rounded bead and in line withthe web, saidlast-mew n'umed bar having 'a curved opening in its web portion of thefirst-mentioned bar, subroimded bead portion, a transverse Opening-stantially as described. in 117s web portipn extending" from the Intestimony whereef I have'signed nay rounded- Opening to? point removedfrom name tq this-specification in the" presence 5 the edge of the web,said.
